Abstract
Measurements of the accumulation of Xel29 from radioactive decay of extinct 1129 in meteorites show that the 1129/ 1127 ratio in high-temperature minerals in diverse chondrites was 10-4 at the time of cooling. The uniformity in the ratio indicates that the minerals cooled simultaneously within 1 or 2 million years.Keywords
